I am still waiting to get my copies (living in the US, I am dependent on a friend in the UK who is travelling here to visit soon. Unfortunately the trip keeps getting postponed, now planned for February. Saves on shipping costs though!)

I would definitely contact Harper Collins about getting a replacement. The bookmarks shouldn't fray like that, straight out of the box. They will give you a higher number than the one you currently have, so if #34 has special meaning for you keep that in mind (but I think a nice bookmark has more lasting value than a particular number in this case.)
